Description_x000D_ Amino Acid Sequence_x000D_ Mpa-Tyr-Phe-Gln-Asn-Cys-Pro-Arg-Gly-NH2 [Disulfide Bridge: 1-6]_x000D_ Application_x000D_ [deamino-Cys1, D-Arg8]-Vasopressin acetate salt hydrate has been used:_x000D_ • in induction of antidiuresis_x000D_ • as agonist of V2-receptor (V2R)_x000D_ • for Von Willebrand factor (VWF) secretion in bleeding diathesis_x000D_ [deamino-Cys1, D-Arg8]-Vasopressin acetate salt hydrate was used to study the impact of vasopressin on pendrin abundance. E3 ubiquitin (Ub)-protein ligases (E3s) was administered in rat kidney and the changes in protein abundance of the selected E3s in response to [deamino-Cys1, D-Arg8]-Vasopressin acetate salt hydrate was examined._x000D_ Biochem/physiol Actions_x000D_ [deamino-Cys1, D-Arg8]-Vasopressin acetate salt hydrate also known as DDAVP, Desmopressin is a selective and potent vasopressor agent that stabilizes the cardiocirculatory function in normal human as well as in patients suffering from catecholamine-resistant vasodilatory shock. It also stimulate three acid-base transporters and hence increases the capability of the cell to regulate pH._x000D_ Preparation Note_x000D_ [deamino-Cys1, D-Arg8]-Vasopressin acetate salt hydrate dissolves in water at 20 mg/ml to yield a clear, colorless solution.
